How Do We Explain Lower Air Temperatures Over The Last 15 Years?

Global warming denialists claim that air temperatures have not risen over the last 15 years.  They use that as evidence to support their denial of global warming.  Scientists cannot explain why air temperatures have not risen over the last 15 years, but they realize that the oceans have always absorbed heat and that ocean temperatures are rising.  This article describes the technology that is enabling scientists to measure water temperatures miles below the ocean surfaces.  Our ability to measure water temperatures even further below the ocean surface will continue to improve.  That will enable scientists to make even more precise estimates in their models which reflect the impact of the increasing concentration of greenhouse gases in the atmosphere.
